Filter apparatus for a kitchen appliance and kitchen appliance

Abstract

A kitchen appliance for the preparation of food includes a filter apparatus. The filter apparatus filters steam generated during food preparation using the kitchen appliance.

1 . A kitchen appliance for preparing food, the kitchen appliance comprising:
 a removable food preparation vessel,   a heating element for heating food in the food preparation vessel,   a tool for mixing or comminuting the food in the food preparation vessel, and   a filter apparatus for filtering steam from the food preparation vessel during a food preparation operation, wherein the filter apparatus comprises:   an inflow opening for steam on an underside of the filter apparatus,
 wherein the filter apparatus encloses a space for receiving a filter material for filtering steam, 
 wherein the filter apparatus is dimensioned such that the filter apparatus is configured to cover a circular opening with a diameter of 6 cm and is configured such that the filter apparatus cannot be pushed through the opening, 
 wherein a largest dimension of the filter apparatus does not exceed 22 cm, preferably does not exceed 15.5 cm, 
 the kitchen appliance comprising a lid for closing the food preparation vessel, the lid having a circular opening, the circular opening having a diameter that does not exceed 6 cm, and 
 wherein, in a filtering position of the filter apparatus, the filter apparatus is positioned on said lid and covers said circular opening completely. 
   
     
     
         2 . A filter apparatus for a kitchen appliance for filtering steam from food preparation with the kitchen appliance, the filter apparatus comprising:

         3 . The filter apparatus of  claim 2 , wherein an outer shape of the filter apparatus is substantially rotationally symmetrical, and wherein the outer shape of the filter apparatus is rotationally symmetrical with respect to a main direction of flow of the steam. 
     
     
         4 . The filter apparatus of  claim 3 , wherein a first dimension of the filter apparatus extending transversely to the main direction of flow is greater than a second dimension of the filter apparatus that extends in the main direction of flow. 
     
     
         5 . The filter apparatus of  claim 2 , wherein the underside is shaped such that the filter apparatus is configured to rest on at least one of an even base or a funnel-shaped base disposed at the underside of the filter apparatus, wherein the at least one of the even base or the funnel-shaped base includes a circumferential contact line or a contact surface. 
     
     
         6 . The filter apparatus of  claim 3 , wherein the filter apparatus includes an outer housing, wherein a material of the outer housing includes plastic, and wherein the outer housing defines the space therewithin. 
     
     
         7 . The filter apparatus of  claim 6 , wherein the filter apparatus includes a lower housing part with the inflow opening and an upper housing part with an outflow opening for filtered steam. 
     
     
         8 . The filter apparatus of  claim 7 , wherein the filter apparatus includes a filter material for filtering the steam, wherein the filter material is disposed in the space. 
     
     
         9 . The filter apparatus of  claim 8 , wherein the filter material is arranged in a filter unit disposed in the space, wherein the filter unit is rotationally symmetrical and includes a circumferential fastening section extending radially outwards, and wherein the circumferential fastening section is configured to couple to an outer housing of the filter apparatus. 
     
     
         10 . The filter apparatus of  claim 9 , wherein a filter material of the filter apparatus includes activated carbon. 
     
     
         11 . The filter apparatus of  claim 10 , further comprising a grille extending over an entire area of the inflow opening. 
     
     
         12 . A kitchen appliance for preparing food, the kitchen appliance comprising:
 a removable food preparation vessel,   a heating element for heating food in the food preparation vessel,   a tool for mixing or comminuting the food in the food preparation vessel, and   a filter apparatus for filtering steam from the food preparation vessel during a food preparation operation,   the kitchen appliance further comprising a suction device configured to suck off steam released from the food preparation vessel during the food preparation operation and direct the steam to the filter apparatus.   
     
     
         13 . The kitchen appliance of  claim 12 , further comprising an electric motor configured to drive the tool, wherein the electric motor is configured to drive a blower of the suction device. 
     
     
         14 . The kitchen appliance of  claim 12 , further comprising a carrying handle for carrying the kitchen appliance, wherein the carrying handle defines a suction opening. 
     
     
         15 . The kitchen appliance of  claim 12 , further comprising a device for separating water from the steam and a collecting tank for collecting the separated water, wherein the device for separating water includes a cooling element for cooling the steam for condensing the water.
